Influence of a Ni, Cu and Cd on the number of filamentous fungi in soil with poplar sprout clones M1, PE19/66 and B229

Abstract

For more than three hundred years heavy metals in addition to pesticides in the last fifty years, represent quantitatively, the most widespread pollutants in the environment. The total concentrationof heavy metals in the living environment is not reflected directly on the degree of their availability to microorganisms, which further complicates an accurate assessment of the risk that heavy metals have in areas where they are present. It is important to point out influence of heavy metals on antibiotic properties of microorganisms. During the experimental work the research was carried out examining the impacts of the specified concentrations of NI, Cu, Cd on the number of microorganisms in the soil with 3 clones of poplar plantations. According to the obtained experimental results, the influence of Ni, Cu, Cd on the number of molds in the soil may lead to an increase in their numbers which is placed in close correlation with the corresponding poplar clones.
